To aZZ whom, it may concern: the shaft and capable of being turned upon Be it known that I, IRA G. BERRY, a citithe same to adjust it to different positions, Zen of the United States of America, residing and when adjusted to the desired position is at Sterling, in the county of hiteside, in the secured therein by means of bolts I, passed 55, 5 State of Illinois, have invented certain new through the beam E and having their inner and useful Improvements in Discharge Atends bent at right angles to engage a ring J, tachments for Fodder- Shredders and the secured to the side of the fan-casing 13, Figs. Like, of which the following is a description, 1 and 3. The ring Jis separated a slight dis reference being had to the accompanying tanc'e from the side of the casing B by inter- 6o 10 drawings, forming apart of this specification. posed spacing-blocks a, so as to permit the My improved discharge attachment, while ready engagement of the bent inner ends of similar in some respects to pneumatic strawthe bolts I with the ring.

Secured Fig. 1. 5 upon the shaft within the casing B is a rotary As will be apparent from the foregoing defan,(shown in dotted lines,) the shaft and fan scription, I have provided a simple and eftibeing driven by a bolt F, passing around a cient pneumatic discharge attachment for small pulley G, secured upon the shaft, and fodder-shredding machines and the like, in around a driving-pulley II of the machine, which the elevation and depression of the 50 Fig. 1. discharge may be easily regulated as desired Thefan-casingl3 is partially supported upon by adjustment of the vertically-arranged fancasing in the manner described, while the lateral discharge may be regulated by means of the nozzle flexibly connected with the discharge-spout of the fan-casing.

I am aware that pneumatic discharge attachments consisting of a casing containing a rotary fan and provided with a dischargespout are in common use with threshing-machines, and perhaps to some extent also with fodder-shredding machines, and I am also aware that it is not new to provide the discharge-spouts of such apparatus with flexible joints composed of short telescopic sections of pipe.

Having thus fully described. myin-vention, I claim- 1. In a pneumatic discharge attachment for fodder-shredding machines and the like, the combination, with the main frame and discharge-chute of such machine, of a vertically-arranged fan-casing supported upon said frame and provided in one of its sides with a central eye or opening adjacent the mouth of the discharge-chute, a dischargespout projecting from said casing, a rotary fan within said casing, and means for adjusting the fan-casing around the fan-shaft and securing it in adjusted position, to elevate and depress the discharge-spout, substantially as described.

2. In a pneumatic discharge attachment for fodder-shredding machines and the like, the combination, with the main frame of the machine having the discharge-chute A and projecting beam E, the vertically-arranged fan-casing 13 having the discharge-spout K, the fan-shaft C journaled in the boxD upon the beam E and extending through a central opening in the side of the casingB and forming an axial support therefor, the fan secured upon the shaft 0 within the casing B, and means for readily securing the casing B to the beam E in its different adjusted position, substantially as described.

3. In a pneumatic discharge attachment for fodder-shredding machines and the like, the combination, with the main frame of the machine having the discharge-chute A and projecting beam E, the vertically-arranged fan-casing B having the discharge-spout K and clamping-ring J, the fan-shaft C journaled in the box D on the beam E and extending through a central hole in the side of the casing B and forming an axial support therefor, the fan secured upon said shaft within the casing, and the bolts I passed through the beam E and adapted to have their inner ends'engage the ring J and clamp the same to the beam E when the nuts upon their outer ends are tightened, substantially as described.
